== OBS Project structure and promotion ==

The Mer projects on OBS look like this:
 Maemo:Mer:Stable
 Maemo:Mer:Stable:HW:Beagle
 Maemo:Mer:Stable:HW:N8x0

This means all devices will have the main 'Stable' repository and an appropriate HW repository.

The development area is expanded slightly:
 Maemo:Mer:Devel:Apps
 Maemo:Mer:Devel:Base
 Maemo:Mer:Devel:MaemoCommon
 Maemo:Mer:Devel:MaemoCommon:L10n
 Maemo:Mer:Devel:UI
 Maemo:Mer:Devel:HW:Beagle:Devel
 Maemo:Mer:Devel:HW:N8x0:Devel

Details of packages in each area is given in the[[Mer/Packages|Packages]] pages.

Packages in each of these Devel subproject areas can be hacked on and then, when they're kinda working they are consolidated into the :Devel area (which is used as a build target for the :Devel:* subprojects)
 Maemo:Mer:Devel
 Maemo:Mer:Devel:HW:N8x0
 Maemo:Mer:Devel:HW:Beagle

Packages are placed in :Testing with the intention of including
them in the next release subject to QA and bug fixes

Maemo:Mer:Testing
  Maemo:Mer:Testing:HW:Beagle
  Maemo:Mer:Testing:HW:N8x0

Once :Testing is ready a release of all packages to a numbered version is made:
  Maemo:Mer:0.13
  Maemo:Mer:0.13:HW:Beagle
  Maemo:Mer:0.13:HW:N8x0

Note that the :HW promotion process is slightly different:
 Maemo:Mer:Devel:HW:N8x0:Devel -> Maemo:Mer:Devel:HW:N8x0 -> Maemo:Mer:Testing:HW:N8x0 -> Maemo:Mer:Stable:HW:N8x0

=== Promotion Tasks ===

To promote a package:
  osc copypac <SOURCEPRJ> <SOURCEPAC> <DESTPRJ>
eg:
  osc copypac -k Maemo:Mer:Devel glib2.02 Maemo:Mer:Testing
The <code>-k</code> ensures that the maintainer info is preserved.

Ensure that:
<nowiki>
  osc meta prjconf <SOURCE>
</nowiki>
is copied to the <TARGET> conf. This may contain things like package selection preferences.
Currently the prjconf is:
 Prefer: hildon-fm-l10n-mr0
 Ignore: hildon-fm-l10n-mr
 Prefer: notify-osd
 Ignore: initramfs:initramfs-tools,udev,blueman
 Ignore: libmbca0:bluez-gnome
 Ignore: libgtk2.0-common:libgtk2.0-0
 Ignore: libgtk2.0-bin:libgtk2.0-0
 # Added following for claws-mail. "have choice for libdb-dev needed by libetpan-dev: libdb4.2-dev libdb-dev"
 Prefer: libdb-dev

== To Promote :Devel To :Testing ==

First pipe over the project metadata:
  osc meta prjconf Maemo:Mer:Devel  | osc meta prjconf Maemo:Mer:Testing -F -

Clean out :Testing
  for i in $(osc ls Maemo:Mer:Testing); do echo $i; osc rdelete Maemo:Mer:Testing $i ; done
  for HW in HW:N8x0 HW:N900 HW:SmartQ HW:Freerunner HW:Beagle; do
    for i in $(osc ls Maemo:Mer:Testing:$HW); do echo $i; osc rdelete Maemo:Mer:Testing:$HW $i; done
  done

Then run:
  osc wipebinaries --all Maemo:Mer:Testing
  for i in $(osc ls Maemo:Mer:Devel); do echo $i; osc copypac Maemo:Mer:Devel $i Maemo:Mer:Testing ; done
  for HW in HW:N8x0 HW:N900 HW:SmartQ HW:Freerunner HW:Beagle; do
    osc wipebinaries --all Maemo:Mer:Testing:$HW
    for i in $(osc ls Maemo:Mer:Devel:$HW); do echo $i; osc copypac -k Maemo:Mer:Devel:$HW $i Maemo:Mer:Testing:$HW ; done
  done

== To Promote :Testing to :Stable ==

The process here is to create a versioned repo; eg :0.14

export STABLE=0.14
  export OLD=0.13

Create the projects (copied from $OLD):
  osc meta prj Maemo:Mer:$OLD | sed "s/$OLD/$STABLE/" |osc meta prj Maemo:Mer:$STABLE -F -
  for HW in HW:N8x0 HW:N900 HW:SmartQ HW:Freerunner HW:Beagle; do
    osc meta prj Maemo:Mer:$OLD:$HW | sed "s/$OLD/$STABLE/" |osc meta prj Maemo:Mer:$STABLE:$HW -F -
  done

Pipe over the project metadata:
  osc meta prjconf Maemo:Mer:Testing  | osc meta prjconf Maemo:Mer:$STABLE -F -

Then run:
  for i in $(osc ls Maemo:Mer:Testing); do echo $i; osc copypac Maemo:Mer:Testing $i Maemo:Mer:$STABLE ; done
  for HW in HW:N8x0 HW:N900 HW:SmartQ HW:Freerunner HW:Beagle; do
    for i in $(osc ls Maemo:Mer:Testing:$HW); do echo $i; osc copypac -k Maemo:Mer:Testing:$HW $i Maemo:Mer:$STABLE:$HW ; done
  done

Allow to build.

<hr>

Then, once it's built and stable, use _aggregate to link each package to :Stable

First clean out :Stable
  for i in $(osc ls Maemo:Mer:Stable); do echo $i; osc rdelete Maemo:Mer:Stable $i ; done
  for HW in HW:N8x0 HW:N900 HW:SmartQ HW:Freerunner HW:Beagle; do
    for i in $(osc ls Maemo:Mer:Stable:$HW); do echo $i; osc rdelete Maemo:Mer:Stable:$HW $i; done
  done

NOTE The following uses -m in osc which is not accepted upstream yet. It will not work unless you have lbt's osc patches.

for i in $(osc ls Maemo:Mer:$STABLE); do echo $i; osc aggregatepac Maemo:Mer:$STABLE $i Maemo:Mer:Stable; done
  for HW in HW:N8x0 HW:N900 HW:SmartQ HW:Freerunner HW:Beagle; do
    for i in $(osc ls Maemo:Mer:$STABLE:$HW); do echo $i
      osc aggregatepac -m MerStable_Debian_5.0=Mer${STABLE}_Debian_5.0,MerStable_Ubuntu_9.04=Mer${STABLE}_Ubuntu_9.04 Maemo:Mer:${STABLE}:$HW $i Maemo:Mer:Stable:$HW
    done
  done

Note that :Stable project must be setup to publish and to build

== Linking to :Extras ==
In order to allow people to develop applications/packages for :Extras they need to setup their home area on OBS as in [[Mer/Build/Application_Building|Building Applications]]. Once the package is built it can be linked to Maemo:Mer:Extras:Devel
  osc linkpac -f -c home:tomaszd84 leafpad Maemo:Mer:Extras:Devel

<code>-c</code> ensures that the version is pinned so when user tomaszd84 changes his package, it doesn't change in :Extras:Devel unless it is relinked.
<code>-f</code> forces an existing link to be updated.

== Linking ==

To link to a source create a _link file containing:
  <link project="linked project name" package="linked package name">

optionally:
  <patches>
    <apply name="name of the first patch" />
  </patches>

Sadly these patches apply to the files in the source; so this means you need to apply the diff to the maemo-ised diff file.
